TRACKING TRANSIENT OBSCURING OUTFLOWS IN AGN

Obscuring outflows are remarkably different from the common warmabsorberoutflows in AGN. They exhibit large columns of highvelocity gas closeto the black hole. They shield much of the Xray radiation, which canhave important implications for the surrounding gas and the launching ofoutflows. Joint ToO observations with NuSTAR and XMM, triggered usingSwift monitoring, have been instrumental for the new results on obscurationevents to come into light. We request a ToO NuSTARobservation (50 ks) to be taken jointly with a XMMNewton observation (50ks), using weekly Swift monitoring of an AGN sample (93 ks in total). truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
